Thermometer Reading

[ghostdawg]

Any idea why my thermometer is showing wrong readings? It seems to be stuck around the 100f range. Heater is set at 75f and 1 month old. It came from Petsmart store!
I had bought a 10 gal tank kit but the original thermometer was broke after opening the box and the store gave me another one, I think it is an Aqua Center brand or something like it.

Thanks.

I’m not sure what kind of thermometer that is but I would say it is faulty because at 100f your fish would be dead. It’s not one of the ones that stick on the outside of the glass is it.

I find one of these are good and vary accurate and not very expensive.

It is the glass type you put inside the tank with the suction cups. I've been reading the digital ones may be better. Which one do you think is better?

Starting a tank is harder then I thought. I should have done my research before starting out. I just thought you buy a tank kit and some fish and live happily ever after!

I do like the digital one myself a little more money but easier and quicker to read. If your thermometer is reading 100f I would say it’s faulty. Have you tried to take it out and shake it down or run some cool water on it and see if it changes and lowers then place it back in the tank and check it again in a few hours.

I haven't tried shaking it down or run some cool water on it, but can try it. I asked Petsmart about it and they do offer a 60 day return on it.
Thanks again.
